So today I had some time to look into my tail issue.
From day one it gives me a CW piro stop bounce. (Never seen with my VBar.)
(CCW is perfect stop.)
I added some degrees offset by shortening my tail push rod by two full turns.
Must be something like 4 or 5 degrees.
I recalibrated rudder end-points using the software.
(Initial settings with zero offset 150-150.)
New settings file is attached.
I was a bit disappointed, the CW piro stop bounce got worse.
For the next flight I changed rudder offset to 2 or 3 degrees or so.
(Lengthen push rod with one full turn.)
We will see...
